ABSTRACT:
An unloading ramp assembly for a vibratory finishing machine of the type having a toroidal bowl or hopper includes an input platform extending to a media separation assembly which in turn extends to an output platform leading out of the vibratory finishing machine. A rod extends across and above the hopper adjacent to the input platform, and a ramp is pivotally engagable with the rod and is adapted to extend downwardly therefrom into engagement with the bottom of the hopper. The insertion sequence for the ramp is initiated by engaging the upper end of the ramp with the rod across the entire width thereof and then engaging the lower end of the ramp with the moving media and piece parts in the hopper, whereby the lower end of the ramp is pivoted downwardly into engagement with the bottom of the hopper. The withdrawal sequence for the ramp is initiated by pivoting one side of the ramp out of engagement with the rod, whereby the moving media in the hopper pivots the ramp out of the hopper. In one embodiment of the invention the ramp is manually positioned, and in another embodiment a fluid powered cylinder is utilized to position the ramp relative to the rod.
